Cracked Lintel Repair Survey

One of our first survey’s of the week to this listed property in the high street of Maidenhead, Windsor.

The brick tower is suffering from lintel failure and the flank elevation has bowed and cracked due to lateral movement following the demolition of the neighboring building.

Lintel Failure

The brick lintels will be reinforced using Twistfix helical bars and Twistfix 450mm CD dryfix pinning ties, the lateral movement will be stabilised using Twistfix lateral restraint ties install in to the existing parallel floor joists along the flank elevation.

Lintel failure and lintel reinforcement

Newman’s have begun a lintel reinforcement scheme for a social housing client in south London to a low level block of flats.

The original timber windows were removed by a glazing contractor who discovered that the brickwork was built without any Intel’s present so upon removal of the frame the masonry above failed causing cracking and sagging.

Helical Rods Are Installed

Twistfix helical rods will be installed between the window openings to repair the masonry and create lintels within the brickwork and pinning ties installed vertically through the last course of bricks pinning it into sound masonry.

Our technicians will be onsite for only one week to allow the glazing contractor to ccarry out their works safely.

Structural repair and structural survey

Newman’s surveyors have carried out  2 interesting structural repair surveys today in London.

The first survey today was to two houses built along the edge a canal in west London. The movement is established as historic settlement causing cracking to the brickwork and altering the load paths resulting I  diagonal cracking above the lintels indicating brick arch lintel failure. In order to restore the failed lintel masonry beams well be installed along with 450mm pinning ties installed vertically through the lintel.

Brick arch lintel failure

The second survey in London was to identify the cause of cracking to this grade I listed tower in central London. The tower is built from 13 inch solid brick work and had substantial areas of cracking. The cause of cracking is a combination of ground settlement, lintel failure and brick damaged caused by freeze thaw cycle. In order to repair the masonry over 1500 metres of helical bar will need to be installed.
